📊 MVP Data Flow Overview

User Registration → Project Creation → Feature Request Submission → Community Voting → Decision Making

Core MVP Flow:

User signs up via OAuth (GitHub/Google)
Project owner creates a project with settings
Users discover public projects
Users submit feature requests
Community votes on requests
Owner moderates and prioritizes
Users track implementation progress

🔐 Authentication Endpoints

1. Get Current User

GET /api/v1/auth/me

Headers:

Authorization: Bearer <JWT_TOKEN>

Test Command:

curl -X GET http://localhost:8080/api/v1/auth/me \
  -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."

Expected Response (200):

{
    "success": true,
    "message": "User retrieved successfully",
    "data": {
        "id": "65f1a2b3c4d5e6f7a8b9c0d1",
        "email": "user@example.com",
        "username": "johnbuilder",
        "name": "John Builder",
        "avatar": "https://github.com/user.png",
        "subscription": {
            "tier": "free",
            "status": "active"
        },
        "created_at": "2024-01-15T10:30:00Z"
    }
}

Test Cases:

✅ Valid JWT token returns user data
❌ Invalid/expired token returns 401
❌ No token returns 401

2. OAuth Callbacks (GitHub/Google)

GET /api/v1/auth/github/callback?code=abc123
GET /api/v1/auth/google/callback?code=def456

Note: These endpoints are typically called by OAuth providers, not manually tested. They should:

Exchange code for access token
Fetch user data from provider
Create or update user in database
Generate JWT token
Redirect to frontend with token

    "values": [
        {
            "key": "base_url",
            "value": "http://localhost:8080",
            "enabled": true
        },
        {
            "key": "jwt_token",
            "value": "{{JWT_TOKEN_HERE}}",
            "enabled": true
        },
        {
            "key": "project_id",
            "value": "",
            "enabled": true
        },
        {
            "key": "request_id",
            "value": "",
            "enabled": true
        }
    ]
}

Import the endpoints using the base_url variable and set up automatic token refresh for seamless testing. This manual provides comprehensive testing coverage for your MVP while ensuring all critical paths work correctly before frontend integration.
